There are 3 ropes to pull but only one is correct and will release your otter girlfriend. Therefore, there's only 1 bad ending medal.
I think the first rope is always correct. In my first run, I pulled the third rope which was wrong. Then pulled the first one in my second run. I also watched a walkthrough and yup, also the first rope was correct. There are no clues, it's just based on luck when you don't know what I just wrote.
What's the point with different endings if all that differs is pulling a random rope?
The game was very short as typical for this developer. My first play trough completion time was 12:13 and second time to get the other ending was 02:49. Puzzles were very easy but fun. Some slight humor makes this a pleasant experience, but on overall feels a bit too mass produced and generic.
That was an easy game. I like the riddle and helping the tenants in the village.
Nice job but why are there two good endings and one bad one instead of two bad ones and one good one?
